WEST L.A. — The eastbound Wilshire Boulevard on-ramp to the northbound San Diego (405) Freeway closed Friday night for 90 days, the final extended ramp closure required for the reconstruction of the heavily used interchange.
According to the Los Angeles County Metropolitan Transportation Authority, which is overseeing the 405 Freeway construction project through the Sepulveda Pass, the existing ramp will be demolished and replaced with one that will have three times more capacity. The new ramp will be 3,129 feet long, compared to the existing 824-foot ramp in hopes of reducing a backlog that traditionally develops at the interchange.
Motorists are advised to plan ahead and seek out alternate routes, including the northbound on-ramp at Santa Monica Boulevard. That ramp has been recently widened to handle additional capacity.
Traffic control officers will be deployed at the Wilshire interchange during peak hours to direct motorists, said Dave Sotero of Metro.
In addition to the Wilshire closure, Metro officials said on Saturday, Aug. 24 they will have to close all northbound lanes and several southbound lanes of the 405 to continue work on the Mulholland Bridge replacement project. The 405 will be closed from 11 p.m. to 9 a.m. Sunday from the Getty Center exit to Greenleaf/Ventura Boulevard. The U.S. Route 101 connector ramp to the northbound 405 will be closed as well.
Officials said emergency vehicle access will be maintained and pedestrians will be rerouted to a safe area outside of the construction zone.
Sepulveda Boulevard will be used as the detour route and no closures will take place on the street.
